I become very itchy after 6 pm. My back, arms, genital area. I want to scratch and scratch and scratch. Then it subsides. I am not red in these areas. I have no bumps, nothing. I have not changed soaps, Deoderants nor laundry detergents. I put all my clothes through a double rinse. I do have a short haired dog, but, I ve always had dogs, long and short hair. I ve gone to my primary care and they said it was environmental. Only at night? After dinner. Is it food? Help!! Thank you VERY MUCH,
